We will be upgrading the software on our primary firewall cluster during the above maintenance window, in order to gain additional functionality and reliability performance.

We anticipate under 1 minute of disruption to production network traffic, but all services at our primary site are at risk for the duration of this window. We apologise for any inconvenience caused by this essential maintenance.

We will be upgrading the Citrix XenServer hypervisor that powers our VPS platform in this maintenance window. This upgrade will allow us to support new operating systems and provides a number of stability and performance enhancements.

Any disruption should be minimal but all VPSs will be at risk for the duration of this window.

In conjunction with engineers from Gyron, we will be migrating all hardware at our primary site, Telstra’s London Hosting Centre, to Gyron’s own Centro Data Centre in Hemel Hempstead. All customer services will be affected during this window.

Sending email servers should queue your inbound email for delivery until the migration is complete. No email should be lost.

No IP addresses, hardware, software or DNS names will change during the migration - this is a physical relocation only - so you don’t need to update any configurations.

We will be performing scheduled maintenance during this window to upgrade the software on our VPN remote access appliance. Only SSL VPN remote access and secure file transfer services will be affected, and not production web or email traffic.

We apologise for any inconcenience this may cause.

Update: This maintenance has been rescheduled.

Update 16/10/2011 22:41: This maintanence is still ongoing and we expect it to be completed shortly.

We will be migrating all our virtual servers at our primary site to new hardware during this window. We don't anticipate more than 60 minutes
of downtime for each virtual server, but we will post updates and any issues on this page.

This will affect VPS, shared and resller hosting services, as well as our own website and billing and support systems. This page will not be affected as it is hosted at our DR site. Most VPS customers will have a change to their package during this window - thse customers have been emailed individually about this.

We will be performing an upgrade of the software on our SSL VPN remote access appliance at this time. Customers who use this service will not be able to log in during the upgrade, and may need to update the VPN client components on their computers after the upgrade is complete. Other services will not be affected.

This upgrade should resolve an issue some customers have seen in relation to SSL certificate chain verification.

We will be performing scheduled maintenance to upgrade the memory in one of our XenServer blades to improve the specification. Most customer virtual machines will migrated to other hosts before this upgrade, but a small number of virtual machines will need to be shut down for around half an hour - we will be contacting those customers affected individually.

All other virtual servers will remain online and unaffected, although all services are at risk during this period due to reduced redundancy and live migration required to move virtual machines off the host being upgraded.

We will be performing scheduled maintenance to upgrade the software on our VPN remote access appliance. Only remote access and secure file transfer services will be affected, and not production web or email traffic.
